Plural Fiber-to-fiber Connections Patents (Class 385/59)
  • Patent number: 10816737
    Abstract: In various embodiments, optical fibers may be placed into V-shaped grooves in a substrate. A lid may then be placed on top of the optical fibers to hold them accurately in place, and the lid may be attached to the substrate using a reflow solder technique. Epoxy may then be applied as a strain relief. Because the V-shaped grooves and optical waveguides are manufactured with precision on the same substrate, precise alignment between these two may be achieved. Because the epoxy is applied after reflow, the epoxy may not be exposed to reflow temperatures, which might otherwise cause the epoxy to distort during the cure process.

  • Patent number: 10168486
    Abstract: A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.

  • Patent number: 10162126
    Abstract: A multi-fiber connector (40) that promotes physical contact with a communicating multi-fiber connector. The multi-fiber connector (40) has a connector body (44) with a front end (47) and a back end (49). The multi-fiber connector (40) also includes a ferrule (10a, 10b) with optical contacts (20a, 20b) at a front end (14a, 14b). The ferrule (10a, 10b) is spring biased toward the front end (14a, 14b) of the connector body (44). The ferrule (10a, 10b) has a pair of alignment pin openings (30a, 30b) extending into the ferrule from a front end (14a, 14b). The ferrule (10b) also has a pair of alignment pins (22) mounted within the alignment pin openings (30a, 30b). The base ends of the alignment pins (22) have a different transverse cross-sectional shape than the alignment pin openings (30a, 30b). This difference in transverse cross-sectional shapes allows the alignment pins to pivot relative to the ferrule along a major axis of the ferrule.

    Abstract: The fiber array assemblies include an interdigitated signal-fiber array supported on a support substrate and formed by front-end sections of first signal fibers interdigitated with either front-end sections of second signal fibers or spacer fibers. The assemblies also include a fiber pusher device that may comprise glass and first and second ends. The fiber pusher device is disposed so that its first and second ends contact and push against first and second edges of the interdigitated signal-fiber array to remove gaps between adjacent signal fibers. A cover sheet is disposed atop the interdigitated signal-fiber array and covers at least a portion of the fiber pusher device to define a ferrule. A securing material is disposed within a ferrule interior to secure the cover sheet, the interdigitated signal-fiber array and the fiber pusher devices. The fiber array assemblies can be connectorized by adding an interconnect device or the like.

  • Patent number: 10048455
    Abstract: Embodiments herein include an optical system that passively aligns a fiber array connector (FAC) to a waveguide in a photonic chip. An underside of the FAC is etched to include multiple grooves along a common axis or plane. Some of these grooves are used to attach optical cables, or more specifically, the fibers of optical cables to the FAC. To do so, the fibers are placed in the grooves and a lid is disposed on the underside of the fibers to hold the fibers in the grooves. The optical system uses other grooves in the FAC to mate with ridges in the photonic chip in order to mechanically couple the FAC to the photonic chip. By registering respective ridges in the photonic chip with grooves in the FAC, the FAC is passively aligned to the photonic chip along at least one optical axis.
